The teen boy, lost in his lustful trance, doesn't hear the trainer enter. The room fills with the scent of oil and the sound of his wet, rhythmic strokes. His big dick glistens, veins popping as he jerks it furiously. The trainer, her eyes gleaming with mischief, takes in the sight, her pussy throbbing at the unexpected but welcome show. She watches, unnoticed, as the boy's body tenses, his cock pulsing with his release.
